What purpose to centrifugation devices resolve in laboratories?

Centrifuge devices come in numerous sizes and are used for different applications, making them a useful device in medical institutions and laboratories.  Nowadays, these devices are compact, made from either plastic or metal and look visually appealing.

These devices are controlled by a timer and have two modes of speed; low and high. Some of the devices available in the market have the capability of keeping the interiors cool, when the appliance is working on high speed.

These devices are used in medical laboratories for separating heavier materials from the solution. It is a laboratory equipment that operates with the help of an electric motor and works on the principle of sedimentation, which causes dense materials to settle down at the bottom, and lighter material to come on the top. These are simple devices, constructed for spinning materials at high speeds, thus causing separation of materials with the help of gravity.

The size of the laboratory and type of procedure that need to be performed in the laboratory will determine the type of Centrifuge that should be used. They are available in different models for carrying out different tasks. Laboratories mainly use two types of centrifuges, which are known as small size and big sized centrifuges.

Bench top and floor standing centrifuges

Bench top are available in small sizes. They are very easy to operate and can be used for separating components of different types of solutions. These small sized devices are the best for laboratories with limited space.

Floor standing centrifuges are sophisticated devices used for processing different types of samples. The best part is that large volumes of samples can be processed at a single time, making them a convenient option to be used in laboratories.

Refrigerated models

Normal laboratory separating devices do not work well for sensitive samples. Using refrigerated models for sensitive samples would be a fair idea to accomplish your objectives.

Besides this, there are many other types that are also used in laboratories for handling different types of solutions such as the following:

1. Preparative

This device is used for separating the organelles of a substance. These centrifuges do not have polar detectors for determining atomic density of the solution. These devices are commonly found in chemistry and biology laboratories.

2. Analytical

These types of devices are used for sampling substances of a solution containing different components. These devices make it easy for scientists to gather maximum information about samples, when they are in the unit.

3. Hematocrit

These centrifuges are used for handling medical blood samples and are comparatively smaller than preparative centrifuges.
